When I started using a Mac for work, the fact that so much functionality which is available free on Linux was now locked behind a paywall in the App Store was frustrating.
Hammerspoon gave me basically all of it back, in a scriptable form which makes it much better suited to what I want. It’s truly great software.
Yah I’ve been able to implement so many different features, and I love doing it myself not just because I don’t have to spend money on software (I’m perfectly willing to do that). I just hate having a myriad of single use third party utilities scattered around my hard drive and cluttering up my OS. I don’t know if I’ve just become more aware, or apps have gotten worse, but so many apps have opaque and undesirable behaviours / scopes nowadays.
